I have a fix for this ticket. The syntax to get
non-contiguous date ranges is to use space-delimited quoted
tokens (see http://tinyurl.com/6e2pqa), e.g.,

"2007-10-29 - 2007-11-30" "2008-11-07 - 2008-11-14" "by month"

Trying to view year-old results alongside week-old results in the
current Reporter can result in 10+ minutes of database thrashing. With
this fix, it's around 30 seconds. If I don't get any bug reports about
the above ~emallove Reporter within 48 hours, I'll push it out to the
main www.open-mpi.org site.
